The most significant change takes place a few weeks after applying the mask in cabin, it improves skin texture and spots decrease noticeably. This can give a misleading feeling of success.
During this period melanin has been removed from the outermost skin layers, and therefore we see the spot much more faded and the skin smoother and softer, but the origin of the problem has not been controlled yet.
The melanocyte, a cell where melanin is produced, is still uncontrolled and continues to produce pigment (melanin) in excess. To re-educate the melanocyte and control this overproduction, it is important to continue a home treatment with regulating action, so that the cell returns to a normal active state and therefore prevent spots from reappearing.
